typedef function paramater miscompiled

[cznic]

This works

int foo()
{
    return 42;
}

int bar(int (*f) ())
{
    return f();
}

int main()
{
    __builtin_printf("%i\n", bar(foo));
}

$ 99c 99c_issue9.c && ./a.out
42
$ 

This does not

typedef int ft();

int foo()
{
    return 42;
}

int bar(ft f)
{
    return f();
}

int main()
{
    __builtin_printf("%i\n", bar(foo));
}

$ 99c 99c_issue9-2.c && ./a.out
